It’s a Python library and it’s main task is to convert low level satellite
data into a format understood by mpop
(http://github.com/mraspaud/mpop). The primary purpose is to support
Geostationary satellite data (level 1.5) but there is also support for the
reading of some polar orbiting SAR data (see below).

A more sophisticated interface to satellite data objects is supported by mpop.

Currently it handles data from all current Meteosat Second Generation (MSG)
satellites, Meteosat 7, GOES 11-15, MTSAT’s, and GOMS, all as retrieved via EUMETCast:

Decompress XRIT files (if Eumetsat’s xRITDecompress is
available). Software to uncompress HRIT/XRIT can be obtained from EUMETSAT
(register and download the Public Wavelet Transform Decompression Library
Software). Please be sure to set the environment variable
XRIT_DECOMPRESS_PATH to point to the full path to the decompression
software, e.g. /usr/bin/xRITDecompress. Also you can specify where the
decompressed files should be stored after decompression, using the
environment variable XRIT_DECOMPRESS_OUTDIR. If this variable is not
set the decompressed files will be found in the same directory as the
compressed ones.
